   Returns a fieldʼs relative maximum value around the current time. The exact
   semantics vary by field, but in the general case this is the value that
   would be obtained if one would set the field value into the
   <a href="intlcalendar.getleastmaximum.html" class="link">smallest relative maximum</a> for
   the field and would increment it until reaching the
   <a href="intlcalendar.getmaximum.html" class="link">global maximum</a> or the field value
   wraps around, in which the value returned would be the global maximum
   or the value before the wrapping, respectively.

   For instance, in the gregorian calendar, the actual maximum value for the
   <a href="class.intlcalendar.html#intlcalendar.constants.field-day-of-month" class="link">day of
   month</a> would vary between <code class="literal">28</code> and
   <code class="literal">31</code>, depending on the month and year of the current time.
